An atomizing spray nozzle device includes an atomizing zone housing that receives different phases of materials used to form a coating. The atomizing zone housing mixes the different phases of the materials into a two-phase mixture of ceramic-liquid droplets in a carrier gas. The device also includes a plenum housing fluidly coupled with the atomizing housing and extending from the atomizing housing to a delivery end. The plenum housing includes an interior plenum that receives the two-phase mixture of ceramic-liquid droplets in the carrier gas from the atomizing zone housing. The device also includes one or more delivery nozzles fluidly coupled with the plenum chamber. The delivery nozzles provide outlets from which the two-phase mixture of ceramic-liquid droplets in the carrier gas is delivered onto one or more surfaces of a target object as the coating on the target object.

The invention relates to an atomizer unit of a minimal quantity lubricant system (2) for a cooling and/or lubricating function of a cutting-machining process. The atomizer unit (3) has a chamber assembly (8) with an injection chamber (9) and an atomizer chamber (10), wherein the injection chamber (9) is connected to the atomizer chamber (10) by a nozzle (11), and the atomizer unit (3) has at least one first feed channel (12) for feeding a first compressed air flow (13) into the injection chamber (9), at least one second feed channel (14) for feeding a second compressed air flow (15) into the atomizer chamber (10), and an injection valve (16) for injecting a coolant and/or lubricant (4) into the first compressed air flow (13) in the injection region (17) of the injection chamber (9). The atomizer unit (3) is designed such that the first compressed air flow (13) flows from the injection chamber (9) into the atomizer chamber (10) through the nozzle (11), is atomized in the atomizer chamber by the nozzle (11), is combined with the second compressed air flow (15) in the atomizer chamber (10) in order to form a transport flow (18) for transporting the injected coolant and/or lubricant (4), and can be conducted to the machining location (7). The atomizer unit (3) has a heater (20) which heats the coolant and/or lubricant (4), the first compressed air flow (13), the second compressed air flow (15), and/or the transport flow (18).

A fan-shaped air suction spray nozzle automatically adjusting an air suction speed is provided in the present invention, which includes a spray nozzle body and a liquid channel, the spray nozzle body being provided with a liquid channel in communication with a nozzle hole, and further includes a pressure groove and an air intake channel, wherein an inlet section of the liquid channel is in communication with the pressure groove, and the air intake channel is in communication with the liquid channel after penetrating through the pressure groove; an air intake orifice plate is installed in the pressure groove through an elastic damping apparatus, and a change of the pressure at an inlet of the liquid channel causes the air intake orifice plate to move between the pressure groove and the air intake channel; the air intake orifice plate is provided with several through holes of the same or different sizes, which are configured to change the air intake volume in the liquid channel as the air intake orifice plate moves in the pressure groove.

Methods are provided for producing an intermittent liquid jet are provided that involve delivering a liquid through a gas dynamic nozzle, which includes an inner tube carrying the liquid, an outer tube carrying a focussing sheath gas, an exit channel and an exit aperture, injecting a stream of the liquid into the exit channel, wherein the liquid is enclosed by the focussing sheath gas in the exit channel, controlling emission of the liquid from the inner tube into the exit channel to produce a periodic, linear intermittent liquid jet including spurts of linear continuous jet sections separated by liquid-free gaps, and output of the intermittent liquid jet through the exit aperture. Furthermore, methods of scattering measurements on samples in a liquid using the method of producing an intermittent liquid jet and an injector device for producing an intermittent liquid jet are described.

Disclosed is a hand piece for an aesthetic and medical device including a first body portion having a cylindrical structure in which a cartridge mounting space a second body portion bound to a lower side of the first body portion and having a cylindrical structure having an upper side on which an air pressure providing portion configured to provide air pressure to the cartridge-mounting space and the auxiliary air flow paths is mounted and a spray head portion bound to an upper body of the first body portion and having a central part on which a spray needle bound to an upper body of the cartridge to upwardly spray the liquid cosmetic product or liquid medication accommodated in the cartridge is mounted.

According to the hydrogen peroxide plasma ionization generator device having a double-jet nozzle suggested by the present invention, the double jet nozzle forming an air passage is configured to construct the hydrogen peroxide plasma ionization generator device such that the hydrogen peroxide and ion particles are sprayed finer than that of a conventional single-jet nozzle.

An aerosol device having a bowl with a bottom defining a drain, and a side wall extending from the bottom to a rim. A nozzle is disposed within the bowl. The nozzle defines a chamber and an outlet orifice directed toward the side wall of the bowl. The aerosol device includes a liquid container fluidly coupled to the nozzle via a first conduit having an outlet tip disposed within the chamber of the nozzle and a second conduit connecting a source of pressurized gas to the chamber of the nozzle. The outlet tip is in the form of a tube defining elongated slots communicating from inside the tube to outside the tube, the slots each having a width defined between two parallel tube surfaces. The aerosol device generates submicron liquid droplets, and is suitable for disinfecting porous articles in an enclosed volume.
